73977380 ÷ 449 
Our goal is to divide 73977380 by 449.

Let's proceed to step 1:
When dividing 7 by 449, we get 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Bring next digit (3) of the dividend behind the 7 and repeat the process: 73 / 449

Advancing to step 2:
The number 449 fits into 73 0 times, leaving a remainder of 73.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 73 and we're left with 73.
Fetch the next digit (9) from the dividend, attach it to 73 and continue: 739 / 449

Let's proceed to step 3:
449 goes into 739 1 times with a remainder of 290.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 449 from 739 and we're left with 290.
Append the next digit (7) from the dividend to 290 and continue with: 2907 / 449

Step 4:
When dividing 2907 by 449, we get 6 with a remainder of 213.
Use 6 as the next digit of our solution. 
Result so far: 16.0
Subtracting 2694 from 2907 leaves us with 213.
Take the next digit (7) from the dividend and append it to 213, then repeat: 2137 / 449

Advancing to step 5:
The number 449 fits into 2137 4 times, leaving a remainder of 341.
Put 4 as the next digit of the answer. 
Result so far: 164.0
Deduct 1796 from 2137 and we're left with 341.
Append the next digit (3) from the dividend to 341 and continue with: 3413 / 449

On to step 6:
449 goes into 3413 7 times with a remainder of 270.
Write down 7 as next digit of the result. 
Result so far: 1647.0
Subtract 3143 from 3413 to get 270.
Take the next digit (8) from the dividend and append it to 270, then repeat: 2708 / 449

Let's proceed to step 7:
449 goes into 2708 6 times with a remainder of 14.
The number 6 becomes the next digit in our result. 
Result so far: 16476.0
The remainder is 14 after subtracting 2694 from 2708.
Bring next digit (0) of the dividend behind the 14 and repeat the process: 140 / 449

Advancing to step 8:
If we divide 140 by 449, we get 0 and a remainder of 140.
Record the quotient 0 as the next digit in the result. 
Result so far: 164760.0
Deduct 0 from 140 and we're left with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Let's proceed to step 9:
1400 divided by 449 is 3 with a remainder of 53.
Use 3 as the next digit of our solution. 
Result so far: 164760.3
Subtracting 1347 from 1400 leaves us with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Moving on to step 10:
449 goes into 530 1 times with a remainder of 81.
Use 1 as the next digit of our solution. 
Result so far: 164760.31
The remainder is 81 after subtracting 449 from 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

On to step 11:
449 can be fit into 810 1 times, resulting in a remainder of 361.
Record the quotient 1 as the next digit in the result. 
Result so far: 164760.311
Subtract 449 from 810 to get 361.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3610, and continue the process.

In conclusion, the division gives 164760.311 with a balance of 0.0361.
